This program takes a parameter, which is how many prime numbers you need. However if you want to make a program which checks whether a number is prime or not you can delete everything in the main function and put this line instead:
cout << isPrime (argv [1]) ? "It's a prime." : "It's not a prime."
Hope you find this useful, if it works correct ;).
#include <iostream>
#include <stdlib.h>
using namespace std;
bool isPrime (float number)
{
if (number == 1.0f) {
return true;
}
for (float i=2.0f; i<number; i+=1.0f) {
if (((number/i) - (int)(number/i)) == 0)
return false;
}
return true;
}
int main (int argc, char** argv)
{
cout << "Hello its me the prime number god!, I will give you " << argv [1] << " Prime Numbers like you requested.\n";
int nums =0;
while (nums != atoi (argv [1])){
static int i =0;
if (isPrime (i)){
cout << "The number : " << nums << " is : " << i << endl;
i++;
nums++;
}else
i++;
}
}
Sorry everybody, I chose C syntax instead of C++.
